I'd agree, but also note that plenty of remote jobs were and still are ad hoc. The difference is adults have more agency to improve their own situation even if their work doesn't make any concessions to the nature of fully remote work; children have very little agency over their schooling.
Public schools are also really limited by the tech they buy, price sensitive, regular staff aren't up to date on tech, and they don't pay their IT teams much.
It makes it hard for them to adjust fast.
The purpose built school from home programs are often far better run / budgeted IT wise. I was at my son's high school and the school from home kids were there for an in person day borrowing the lab for some in person time / activities and etc.
